It has been a typically slow start to the AFL’s Exchange Period, but the Sydney Swans remain keen to secure Adelaide Crows midfielder Tony Armstrong.

Speaking to afl.com.au's Trade Week Radio today, Swans coach John Longmire confirmed that the Club's recruiting manager, Kinnear Beatson, had commenced discussions with Adelaide to secure the skilful 22 year-old.

Talks slowed early in the week, with Adelaide busy negotiating a number of other deals. With the Crows deal on young forward Jack Gunston now complete, Longmire said the clubs could now turn their attention to making Armstrong a Swan. 

“We hope so," Longmire said when asked about getting the deal for Armstrong done. "That’s what we’re trying to work towards."

"It may take a bit of time. We’re keen to get it done but need to obviously work through that with Adelaide at the moment."

Longmire also confirmed that Port Adelaide had shown interest in ruckman Mark Seaby.

With a reluctance to play two ruckman under the new substitute rules, Seaby struggled for opportunities at senior level in 2011, playing just seven matches.

“He still played some reasonable footy for us this year when he was able to get the chance," Longmire said of Seaby. 

"He is probably one who has been a little bit affected by the sub rule, I guess. 

“Port have shown some interest but we just have to wait through that as well. It hasn’t progressed too far as yet.”

Trade week concludes at 2pm on Monday October 17.
